ABSTRACT:
A manually operated dispensing pump is provided for delivering a precise quantity of ophthalmic solution to the surface of the eye in a desired spray pattern with an impact pressure on the eye that is comfortably tolerable by an individual. The dispensing pump basically comprises a push button actuator having a nozzle member disposed therein, a cap member for receiving the push button actuator and having a control ring for selectively limiting the downward travel of the actuator, and a pump chamber engaged in the cap member and in communication with the push-button actuator for pressurizing a metered quantity of ophthalmic solution.
